"A safety audit was completed and speed humps were installed, in consultation with the school, as a physical means to calm the traffic."
Castlecliff School Board chairman Jeff Slight said it's a great outcome for the safety of students.
"We have been trying to get something sorted for several years and this came to a head after a crash that resulted in the death of a driver outside our school last year.
"The outcome was to have speed humps either side of the crossing."
Thirteen-year-old Keanu Josephs-Ranginui died in June 2018, when a fleeing vehicle he was a passenger in crashed into a tree near the school.
Following the crash Polson St residents Robin and Frances Abbott called for more safety measures to be put in place on the street.
At the time they suggested measure needed to be put in place to slow the traffic.
"It's a race track, the speed they travel down here, if they went through your fence, which they would like match wood, they would actually hit your house," Robin said.
"The school being so close is just diabolical. If kids try and cross the road here, I've seen them, they're putting their lives at risk."
